Careful or you'll catch the mod bug like i did O.o!! lol
Are you only wanting to put on a CAI or do you want to go further eventually? if you want to go further, save up your money and buy a CAI that requires a Tune
try bamachips or brenspeed, and look at their CAI/tune packages.
i believe Bama runs for about 620 for the package with the CAI tuner and 3 tunes.
if you don't want to go further look for a cheaper CAI that doesn't require a tune, i.e. AEM. they will defiantly make your car sound a lot more aggressive, no matter what you get.
take your time finding the exact thing you want so you don't end up spending hundreds of dollars on something that you hate.
